My gut feeling is that the ICP was slowly deteriorating, choking off the
current as the unit played, then "recovering" as it sat overnight.
Have you seen anything like that?

I've seen them go high resistance rather than totally open, but not
intermittently as far as I can recall. Are they the little TO92 style
ones
?
If they've got an "N" number for the rating, I guess they are.

No, they're more like little rectangles than flattened cylinders.



OK. I guess that I've probably come across such at some time, but not
commonly. The ones that I most often see, are the TO92 style ones, and the
little yellow cylinder ones with rounded ends. Both of those types fail for
no apparent reason, so I guess there's no reason why your type shouldn't do
the same, either.
